MEANS FOR SEPARATING SOLID SUBSTANCESjFRQM,LUBRICATING-OIL.

Application filed July 23,

Z aZZau/wm it may concern.

Be it known that I, F RANK E. Knvns, a citizen of the United States, and a resident of Pasadena, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Means for Separating Solid Substances from Lubricating-Oil; and I do hereby declare the following to be a full, clean-and exact description of the invention, such as 'will enable others skilled'in the art to which it appertains to make and use the same.

This invention relates to means for separating solid substances from lubricating oil, -one object of the invention being to provide a simple and efiicient trap device which shall be applicable to the crank case of an engine, such as an internal combustion engine installed in automobiles, or to a pipe of a lubricant circulating system, and operate to cause the lubricating oil to so circulate through said device as to arrest and collect any solid particles, such as carbon, grit or sediment of any kind which may be heavier than the lubricating oil.

A further object is to construct the device in such manner that its effective and continuous operation to separate solid particles from lubricating oil in use in the crank case or the lubricant cinculating system of an engine, shall be insured by the movement of the oil during the operation of the engine or circulating system.

Vith these and other objects in View, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a trap device showing an embodiment of my invention. Fig. 2 is a longitudinal sectional view, and Fig. 3 is a transverse sectional view on the line 33 of Fig. 2.

1 represents a receptacle which may have a general tapering shape and is provided at its smaller end with a threaded nipple 2 disposed at right angles to the body of the receptacle and adjacent to this nipple an angular portion 3 is provided for the reception of a wrench whereby the nipple may be screwed through a suitable hole in the bottom of a crank case orinto the pipe of a lubricant circulating system.

. A vertical partition 4 is provided centrally Specification of Letters Patent.

within the nipple 2 and extends downwardly into the smaller end portion of the receptacle and forms two ducts, each open at both ends, said' partition also projecting upwardly beyond the end of the nipple so that when the device is applied to the crank case or circulating pipe, said upwardly projecting portionof' the partition, indicated at 5, will enter said crank case or pipe so as to be disposed in the path of movement of the lubricating oil during the operation of the engine. The circulation of the oil, caused either by the operation of the engine crank or by the flow through a circulating pipe, will cause the oil to How against the portion 5 of the partition or baffle and to be directed by the latter downwardly into the receptacle, through which latter it will circulate and find an exit at the other side of said partition or battle and will thus be directed back into the crank case or circulating pipe. During the circulation of the oil through the device, as above explained, any solid particles, such as carbon, grit or other sediment will become deposited within the receptacle and the oil reentering the crank case or pipe will have been effectually freed from such foreign matter and will be in condition to lubricate the engine without such injury thereto as would be caused if such foreign permitted to remain in the substances were oil. The effective separation of foreign substances from the oil will be greatly facilitated by reason of the fact that the oil during its use in the engine will be somewhat highly heated and therefore of thin consistency.

The collected solid substances or sediment in the receptacle may be readily withdrawn from time to time (preferably once a day) by means of a manually operable valved cock 6 located at the larger end of the receptacle as clearly shown in Fig. 1.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is:

l. A device of the character described, comprising a receptacle provided near one end with an upwardly extending nipple, and a partition in said receptacle, said partition extending through said nipple and upwardly beyond the same.

2. A device of the character described, comprising a receptacle provided near one end with an upwardly extending nipple disposed approximately at right angles to the body ring system, comprising a receptacle having a connection adaptable to a crank case or circulating pipe, and provided therein with a partition extending through said connection and having a part to project into said crankcase or pipe.

4. A device of the character described coniprisinga receptacle provided at one end with a. nipple disposed at an angle thereto and adapted for connection with a crank case or circulating pipe, in said nipple and entering one end of the receptacle,' said partition forming two ducts each open at both ends, and said partition and a partition having a part projecting upwardly beyond the end of the nipple.

5.9x device of the character described comprising a receptacle having a part for connection with a crank case or circulating pipe, and a partition disposed in the part of the device which is adapted for connection with the crank case or circulating pipe, said both ends, and'said partition having a part projecting beyond the receptacle and adapted to enter within the crank case or circulating pev In testimony specification in ing witnesses.
